The petition shall include sufficient and appropriate data, as determined by the administrator, such as nitrogen oxides emissions from the affected facility, waste composition (including nitrogen content), and combustion conditions to allow the administrator to confirm that the affected facility is unable to comply with the emission limits in
par. (e) and to determine the appropriate emission limit for the affected facility.
NR 440.205(5)(f)1.
1. Any owner or operator of an affected facility petitioning for a facility-specific nitrogen oxides emission limit under this subsection shall:
NR 440.205(5)(f)1.a.
a. Demonstrate compliance with the emission limits in the
par. (a) table for natural gas and distillate oil or for residual oil as appropriate, by conducting a 30-day performance test as provided in
sub. (7) (e). During the performance test only natural gas, distillate oil, or residual oil shall be combusted in the affected facility; and
NR 440.205(5)(f)1.b.
b. Demonstrate that the affected facility is unable to comply with the emission limits in the

2. The nitrogen oxides emission limits in the
par. (a) table for natural gas or distillate oil or for residual oil, as appropriate, shall be applicable to the affected facility until and unless the petition is approved by the administrator.

40 CFR part 261 or
40 CFR part 761, as in effect on July 1, 1994, with natural gas or oil may petition the administrator within 180 days of the initial startup of the affected facility for a waiver from compliance with the nitrogen oxides emission limit which applies specifically to that affected facility. The petition shall include sufficient and appropriate data, as determined by the administrator, on nitrogen oxides emissions from the affected facility, waste destruction efficiencies, waste composition (including nitrogen content), the quantity of specific wastes to be combusted and combustion conditions, to allow the administrator to determine if the affected facility is able to comply with the nitrogen oxides emission limits required by this subsection. The owner or operator of the affected facility shall demonstrate that when hazardous waste is combusted in the affected facility, thermal destruction efficiency requirements for hazardous waste specified in an applicable federally enforceable requirement preclude compliance with the nitrogen oxides emission limits of this subsection. The nitrogen oxides emission limits in the
par. (a) table for natural gas or distillate oil or for residual oil, as appropriate, are applicable to the affected facility until and unless the petition is approved by the administrator.

sub. (3) (d) 1., shall demonstrate the maximum design capacity of the steam generating unit by operating the facility at maximum capacity for 24 hours. This demonstration will be made during the initial performance test and a subsequent demonstration may be requested at any other time. If the 24-hour average firing rate for the affected facility is less than the maximum design capacity provided by the manufacturer of the affected facility, the 24-hour average firing rate shall be used to determine the capacity utilization rate for the affected facility, otherwise the maximum design capacity provided by the manufacturer shall be used.
NR 440.205(6)(f)
(f) For the initial performance test required under
s. NR 440.08, compliance with the sulfur dioxide emission limits and percent reduction requirements under
sub. (3) is based on the average emission rates and the average percent reduction for sulfur dioxide for the first 30 consecutive steam generating unit operating days, except as provided under
par. (d). The initial performance test is the only test for which at least 30 days prior notice is required unless otherwise specified by the department. The initial performance test is to be scheduled so that the first steam generating unit operating day of the 30 successive steam generating unit operating days is completed within 30 days after achieving the maximum production rate at which the affected facility will be operated, but not later than 180 days after initial startup of the facility. The boiler load during the 30-day period does not have to be the maximum design load, but shall be representative of future operating conditions and include at least one 24-hour period at full load.
NR 440.205(6)(g)
(g) After the initial performance test required under

sub. (7) are achieved. All valid emissions data, including valid sulfur dioxides emission data collected during periods of startup, shutdown and malfunctions, shall be used in calculating %P
s and E
ho pursuant to
par. (c).
NR 440.205(6)(i)

sub. (3) (i), emission data are not used to calculate %P
s or E
s under

sub. (3) (i).
NR 440.205(6)(j)
